The xcd command displays a graphical representation of a compact disk
player's control panel using X-based Motif windows. The display includes a
main key pad with keys for PLAY, STOP, PAUSE, EJECT, NEXT TRACK, PREVIOUS
TRACK, DISK ACCESS LOCK, REPEAT MODES, SHUFFLE MODE, and QUIT. A status
window displays track and time information. A set of selection buttons,
one for each track of an inserted CD, allow you to directly select a track
to be played. The selection buttons double as a display of the play
sequence with track now playing highlighted. A volume slider adjusts
output volume across a scale of 0-100. The volume control on the CD drive
itself should be set to full.
To use this program you need a workstation with a Compact Disk drive. The
xcd program is not supported.
Most of the buttons on the control panel are self-explanatory. One,
however, may not be obvious. The padlock button may be used to disable the
eject button on the front of the CD drive. This can be used to discourage
someone from ripping off your CD.
You can customize some aspects of xcd's appearance by specifying xcd
resources in your ~/.Xdefaults file. Use the Xcd file as a template. This
file is found in the /usr/lib/X11/app-defaults/ directory.
xcd will attempt to find the cd player on your machine. If you have
multiple CD-ROM players on your machine, it will use the first one found.
The method it uses is to start scanning the bus using CAM from low to high,
so the lowest numbered CD-ROM on the lowest numbered bus will be the
selected device. To override this selection, set the environment variable
CDROM or the -cd option which will override this mechanism. For the
automatic location of the CD device to work you must have read permission
on the /dev/cam device. As superuser you should:
# chmod 644 /dev/cam
You will need to have the permissions of your CD-ROM device changed to
allow proper operation. In our example we will use /dev/rrz4c. As
superuser you should:
# chmod 666 /dev/rdisk/dsk4c
You can tell xcd where the CD-ROM drive is. You can do this by either
setting the environment variable CDROM to the device, or by starting xcd
with the -cd option. For example:
# using the environment variable (csh)
% setenv CDROM /dev/rdisk/dsk4c
# using the '-cd' option
% xcd -cd /dev/rdisk/dsk4c
Or you can let xcd figure out where the CD-ROM is.
